The communication cable that leaves the motor will run to one battery, and this cable will connect the batteries to each other. Kit includes one cable and two terminators. Compatible with the ePropulsion E60, E163 and G102 batteries. Available in 5m, 1.5m and 0.5m lengths. If you need this kit, you'll also need an ePropulsion E Battery Bridging Cable.
